Programming Modes

The CN-TVAV may be utilized three ways to perform different functions; Local,

Remote, and Mixed Processing Modes. Similar to as shown below, the CN-TVAV

and its supporting devices have been added to SIMPL Windows.

New SIMPL Windows’ Devices for Programming the CN-TVAV

NOTE: The CN-TVAV contains no NVRAM. It has “simulated” NVRAM,

meaning that conventional (volatile) memory is mapped into the NVRAM space.

When power is disconnected, the contents of memory are lost. Rather than restrict

the usage of NVRAM symbols (such as RAM, SMEM, etc.), the mapping allows

some SIMPL programs to use NVRAM for runtime calculations. Runtime

calculations are not essential if power is lost and are reset at startup (i.e. such as

putting names into an SMEM when using the QUE symbol).

NOTE: The CN-TVAV also does not have a hardware clock. The clock must be

reset at startup.

NOTE: The compiler will detect usage of NVRAM symbols or DEVICE SYSTEM

(real time clock driver) and flag it in the error log as warnings when programming.
